With Flash I can play games for a reasonable amount of time, at a reasonable fps, with reasonable load times, and a reasonable quality before my computer slows considerably. With these games it's the contrary.

All of these HTML5 games lack ambition. None of them seem to have the gameplay, fun-factor, playtime, or cohesiveness of say... original Super Mario Brothers. Apparently Freeciv online [slashdot.org] wasn't submitted, but I think it has a lot more polish and overall completedness than any of these submissions. Personally, I think the future of HTML5 gaming is wide open

...aside from the fact that they do server-side user-agent detection and require specific versions of Firefox. Cool concept, but that's neither a web game or an HTML5 game, it's a Firefox game. They might as well have used XUL.

Got a 502 error on far7 and two of the others didn't load. I opened up web snooker only to be told that my Webkit nightly of Safari isn't supported and I need to "update it." The only one that worked for me was z-type–fun, but only for a little while.

Yeah, Far 7 is a good start. But, I saw limited ability for strategy... compare to say, tradewars where you could control sectors, form alliances, and build up a little empire. I'm just saying, I was hoping for more.
